The external prestressing force system is the most important part in the external prestressing force bridge structure. On the basis of at external prestressing force structure the understandings of developing directions, and Liuzhou Europe link science of bridge building department mechanical Co., Ltd. since the end of 1990s nurse Tongji University, Begin, Go on a large amount of science and deep research and has made certain achievement. The composition of a set of intact external prestressing force systems should include : External prestressing force anchor careless systemses, external prestressing forces turn to ,, external prestressing forces protect external prestressing force cable wires and external prestressing force reduce the shaking machine system device.

The main technological characteristic of OVM external prestressing force system: 1)Single roots can wear and ask for, not single root draw , single roots adjust and ask for , the single root is transfer to asking for by one; 2)Freedom section has not formed a vesicle, easy to use to external cable wire measuring in the course; 3)It is small to turn to the radius, it is not the horizontal baffle size that intensity causes that the maximum is reduced. 4)Turn to place entangle line even to receive strength, reduce centralized stress by each a stick of steels.

System specially for having oneself protect external prestressing forces the single rootses of ability have and glue and form OVM, Utilize the steel entangle line can operate, antiseptic performance kind merits independently to the maximum extent. In a strict one being antiseptic to require and down, system propose select itself for use with multilevel shelter the whole spraying entangle line by steel oxygen rings. In addition, OVM external prestressing force system has a kind to utilize the finished product to ask for technology, Please consult OVM company in details.

Corpus outside prepare stress system is corpus outside prepare stress bridge structure amid suprema constitutive enzyme part.Owing to corpus exoenzyme prepare stress structure development direction of recognize, homo -  university bridge engineering system and LiuZhou state OVM machine limited liability syndicate auto -20 age the end of 90's, then beginning vs corpus exoenzyme prepare stress structural behaviour, corpus exoenzyme prepare stress steel cord of rot proof subject, anchor of anchor  performance and antienzyme fatigue performance iso - everyone face, steer bulk analysis science but thorough of research, amalgamation acquirement definite fruit.
A set integrity of corpus exoenzyme prepare stress system of constitutive enzyme should include:Corpus exoenzyme prestress anchoraging system, corpus exoenzyme prepare stress sway apparatus, corpus exoenzyme prepare stress steel cord, corpus exoenzyme prepare stress protecting system sum corpus exoenzyme prepare stress shock absorber.
OVM corpus exoenzyme prepare stress system of main technique characteristics:
1) can unipole indogen wear cord, unipole indogen sheet pull, unipole indogen adjust cord, unipole indogen change cord;
2) freedom zone none grouting, easy to use course amid vs corpus exoenzyme steel cord of detection;
3) sway semidiameter small, maximum limit let up not strength station with the result that of transverse diaphragm size.
4) sway section per indogen steel stranded wire suffer towing force blance, slow stress concentration.
OVM corpus exoenzyme prepare stress system just for have oneself protecting capacity of unipole indogen none packing prepare stress steel stranded wire design of, amalgamation maximum limit land utilization use this kind of steel stranded wire can independence working, rot proof performance good merit.At stringency of rot proof solicit down, system submittal application per se have polypeptide lay protecting of cyclo - oxidase holoenzymes spray gun draw steel stranded wire.
Moreover, OVM corpus exoenzyme prepare stress system repay have a category pattern is take advantage of completed product cord technical, details please advisory conciliation and arbitration service OVM syndicate.
